Check Digit Verification of cas no

The CAS Registry Mumber 74734-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,3 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74734-33:
(7*7)+(6*4)+(5*7)+(4*3)+(3*4)+(2*3)+(1*3)=141
141 % 10 = 1
So 74734-33-1 is a valid CAS Registry Number.
